Frequently Asked Questions About International HX Leaf Springs, Hangers & Acc.
What International HX model years are these leaf springs compatible with?
Our leaf springs are designed specifically for International HX Series trucks from 2017 to present. This includes the HX515, HX520, and HX620 models. Each product listing specifies exact compatibility, as spring configurations can vary based on your truck's GVWR, wheelbase, and suspension type (single or tandem axle). Always verify your truck's VIN and specifications before ordering to ensure proper fitment.
Are these leaf springs OEM quality or aftermarket replacements?
We carry both genuine OEM International parts and high-quality aftermarket alternatives. OEM springs are manufactured to International's exact specifications and tolerances. Our aftermarket options are made from premium spring steel that meets or exceeds OEM standards, often featuring improved corrosion resistance through powder coating or e-coating. Many customers report aftermarket springs lasting as long as OEM at a more competitive price point.
What tools and equipment do I need to replace leaf springs on my HX?
Replacing leaf springs requires heavy-duty equipment including a minimum 20-ton hydraulic jack, jack stands rated for commercial trucks, spring compressors, and an impact wrench capable of 1,000+ ft-lbs of torque. You'll also need new U-bolts (never reuse old ones), bushings, and shackle pins. Most shops charge 4-6 hours of labor for a complete spring replacement. Due to safety concerns and specialized tools required, we recommend professional installation unless you have commercial truck experience.
How do I know when my leaf springs need replacement?
Common signs include visible cracks in the spring leaves, sagging on one side causing uneven ride height, excessive bouncing or harsh ride quality, and broken or separated leaves. Also check for worn eye bushings causing clunking noises, rust penetration beyond surface level, and any leaves that have shifted out of alignment. If your truck leans more than 1 inch side-to-side when unloaded, spring replacement is typically necessary.
What's included with the leaf spring assemblies, and what additional parts might I need?
Most complete leaf spring assemblies include the main spring pack with factory-correct number of leaves, front eye bushing, and rear shackle bushing. However, you'll typically need to purchase separately: U-bolts and nuts, shackle kits, center bolts, wear pads, and potentially new hangers if yours show wear. We recommend replacing all wear components during spring installation to avoid premature failure and ensure proper suspension geometry.
